| description | The invention discloses a suspending agent for high-temperature and high-density oil-based disposal fluid and a preparation method of the suspending agent, and belongs to the technical field of petroleum and natural gas drilling. The suspending agent for the high-temperature and high-density oil-based disposal fluid is prepared from the following components in parts by mass: 20-50 parts of styrene, 5-10 parts of a chloromethylation reagent, 50-80 parts of acrylic acid long-chain alkyl ester and 1-2 parts of carbon fiber powder. By using the suspending agent disclosed by the invention, the sedimentation stability of the high-temperature and high-density oil-based discarded fluid can be effectively improved, and the risks of high-temperature and high-pressure oil gas invasion, series flow and blowout caused by solid-liquid layering, solid-phase sedimentation and sand setting of the underground high-temperature and high-density oil-based discarded fluid for an offshore deep well, a high-temperature well, a highl |
